FIXTURE SUPPORT.

Application filed February 17, 1928. Serial no. 619,549.

My invention relates to a support for fixtures and the like and isparticularly adapted to securing to a wall or ceiling articles such asbath room accessories, electric light fixtures, and other devices inwhich it is desirable to so secure the device to the wall that thesecuring and supporting means shall be concealed from View.

A considerable difficulty has been experienced in securing fixtures ofthis class to a wall or ceiling in a substantial manner, since,heretofore the usual practice has been to secure such fixtures by meansof screws passing therethrough into plugs, expansion olts, or the like,fastened in the wall. This has involved accurate drilling of relativelvsmall holes which frequently resulted in the cracking or othermutilation of the wall and produced an attachment which lacked strengthand was frequently unsightly.

According to my invention I am enabled to firmly attach fixtures to awall of cement, plaster or similar material, and my improved device isarranged so that the upported fixture is, through the attaching means,drawn into close contact with the wall. When attached no screws or otherattachin means are visible.

In t e drawings accompanying this specification I have shown In Figure1, a cross sectional view of one form of my invention,

In Figure 2, a plan view thereof,

In Figure 3, a cross sectional view of a modified form of my invention,and

In Fi ures 4 and 5, vertical and cross sectional views of anothermodification thereof.

Referring to the drawings, it will be seen that my device comprises asupporting member 1 and a supported member 2, the supporting memberbeing embedded in the wall :3. The wall may be faced with tile 4, orother similar material and the supporting member is inserted in the wallby drilling r a relatively large recess 5, which need not be of anyexact dimensions, filling said recess with plaster of Paris or othersuitable material and inserting the supporting memher 1 therein. i

The supporting member 1 is provided with lateral extensions 6,of the shae shown, and to permit easy entrance oftne lateral extensions throughthe plaster of Pariswhile the same is still in a plastic condition.-

but to prevent the supporting member from Paris t e plaster of Parismaybe easily displaced but that when it is attempted to withdraw it itis wedged between the wings 7 and the other portions of the supportingmember toform a substantial anchor.

Mounted upon and fixed to the shaft of member 1 is a disk 8 which vactsto prevent the material 5 from being forced out of the recess when theend of member 1 is inserted withm said recess. The disk 8 also serves tolimit the positionin of the entire member 1, which, as has iiefore beenstated is the supporting member. As shown in Fig. 2, the dlslr 8, may,and preferably does have a lug or 11p formed on the edge thereof. Thelug or 11p 9, it will be obvious, serves to position the supportedmember 2 and to prevent rotation of the latter, by being fitted within arecess 9' formed in member 2, as clearly shown in Fig. 2. It will alsobe obvious that if the member 1 is embedded in the wall with regard tothe position of this lip 9, the member 2 will have a correspondinglycorrect position when attached to the member 1. The supported member2isadaptedto cover the exposed portion of the supportmg'member as showninthe drawmgs, and is provided with suitable means, such as set screw11, for engaging the supporting member. The latter ad acent its exposedend is formed with a taper which may take the form of an annular groove13 as shown in Fig. 1. The arrangement is such that the tightening setscrew in engagement with the taper will force the supported member inthe direction of the wall and thus insure a tight fit between thesupported member and the wall. It will also be noted that all of thefastening means are covered by the flange on the supported member, andthat the only fastening member exposed is the head of the set screw 11,which may' be put in an inconspicuous position. When desired, a portionof the same fastening means may be used, as shown in Fig. 3, in whichmodification the disk or plate 8 is'attached to thewall by means ofscrews 12, and the anchor portion of the supporting member omitted.

The modification in Fig. 3 is adapted for use on wood or metal, or othersubstances in which screws can obtain a firm hold and which it isinconvenient to drill and fill with plaster as described above inconnection with the modification of Fig. 1.

If desired, the lip 9 may be omitted and the set screw or other meansmay be used to perform the functions of the lip as well as the otherfunctions performed by it. Such an arrangement is illustrated in Figs. 4and 5 in which modifications a tapering slot 13 is cut in the supportingmember, with which slot the set screw or other means carried by thesupported member cooperates. It will be understood that thismodification is applicable equally to the device shown in Figs. 1 and 3and that, if additional precautions against rotation are desired to betaken, the lip may be used as well. If the modification of Figs. 4 and 5is used, the disk 8 may be entirely omitted or a laterally extending pin14 or other similar device for positioning the supporting member may beused, although I find the disk 8 useful because it positions thesupporting member normal to the line of the wall without the exercise ofany great care on the part of the user.

While I have only described the forms of my invention which I refer andhave found use for in practice, I 0 not wish to confine myself theretoas it will be evident to those skilled in the art that manymodifications may be made without departing from the spirit of myinvention.

It will be noticed that by a very simple structure I attain importantresults, that is, I get an easy, rigid and permanent assembly. Infixture supports, generally, the supported member'has been inclined towabble more or lessv in some cases to a considerable extent and in somecases only sli htly on its supporting member. This web lin ultimatelyresults in the supported mem er becoming loose, either by disturbing thesupport or by loosening the fastening screw and the fixture ultimatelyfalls apart, or becomes shaky or ugly in appearance. Where the two partsare fastened together by a set screw going through a part of thesupported member and into the supporting member,'as, for example, in thestructure shown in the patent. to Wells No. 1,27 6,463 of August 20,1918, it is diflicult to have the fastening or binding screw registeraccurately with the hole in the stem, which it is supposed to enter andtherefore it is difficult to assemble the structure, Moreover, in astructure of this kind there is likely to be more or less play at thebase of the supported structure and between it and the wall with whichit abuts, so that this will cause vibration and wabbling. In otherstructures the stem of the supporting member has been made in two piecesto provide for expanding the stem, and, to a slight extent, foradjustment of the supported member, but structures of this kind areundesirable because of the fact that the stem does not transversely fillthe socket of the supported member as it should and reliance has to behad on the fastening screw, and wabbling and vibration result.

Furthermore, the multiple part structure is objectionable because of theexpense and the fact that the parts are likely to be im-' properlyfitted or become dis laced or lost in shipment. All these difficultiesare overcome bymy improved structure.

It will be noticed that the stem 1 is of the same cross-sectional shapeand transversely fills the socket of the member 2 and that the inclinedsurface of the stem, when engaged by the screw 11, causes the base ofthe part 2 to be brought into firm contact with the adjacent wall sothat the parts are held against possible loosening. This, rigidity ofstructure is further enhanced by'the fact that the lip 9 on the edge ofthe member 8 engages a complementary part 9 in the member 2, so thatwhen the latter is positioned it cannot turn and it cannot movelengthwise. To get at this result it has sometimes been the practice tohave a lug on the face of the part marked 8, correspond-v ing with acomplementary socket in the wall of the member 2, but this structure isobjectionable for the reason that it is difiicult in (practice to havethe partsalw'ays register an to brin them into proper connection. Byhaving t is lip on the edge of the member 8, however, it is a simplematter to turn the member 2 so that the recess 9 will register withthe'part 9, and thus when the structure is erected there is nopossibility of the fixture turning or movin axially and, consequently,the erection o the parts is easy and permanent.

What I claim is:

1. A fixture support comprising a supporting member having a rigidone-piece stem. with a recessed part, the outer wall of which isinclined towards the base of the stem, means for attaching thestem to asupport, a supported member having a socket which fits over the stem ofthe su porting member so that the stem substantial 1y fills the sockettransversely, and, a fastening member carried by and adjustable in thesupported member intersecting the socket and impinging on the outerinclined wall only ofi the recess of the stem thereby moving thesupported member endwise towards its base.

2. A fixture support comprising a supporting member having a' rigidone-piece stem with a circumferential recess therein, the outer wall ofthe recess being inclined toward the base of the stem, means for atlulltaching the stem to a sup member having a socket w ich fits over thestem of the sup orting member so that the stem substantiai y fills thesocket transversely, and a set screw carried by and "adjustable in thesupported member intersecting the socket and impinging on the enterinplort, a supported clined wall only of'the recess of the stem therebymoving the supported member endwise towards its base. 4

In testimony whereof, I have signed my name to this specification this5th day of February, 1923. a
